Taking out last character in a variable

[Adamthenewbie]

I have a variable that I am using to make an email list. Here is the code

$emailList = $emailList . $row[0] . ", ";

This loops and works but I have an , at the end. Is there an easy way to delete the last character?

Thx

$emailList = substr($emailList,0,-1);

doesnt seem to work??

Well, you actually need to remove the last 2 characters, since you're adding a comma and a space.
